SELF-LOCKIN G FRUIT BOX.

Application led December 20, 1926. SerialI No. 156,006.

This invention relates to packing receptacles and pertains particularlyto a collapsible box intended primarily for holding fruit, such asberries or the like.

A primary object of this invention is the4 rovision, 1n a manner ashereinafter set Forth, of a collapsible box of such construction thatthe same may be made of cardboard, but will have all the strength andstability of a wooden box.

Another object of the invention is the provision, in the manner ashereinafter set forth, of a folding box which can be constructed ofcomparatively inexpensive ,material and though inexpensively made willnot lack any of the good=qualities of other boxes of this characterwhich are constructed of more expensive material.

Another object of this invention is the provision in a mannerhereinafter set forth, of a box which may be easily and quicklyassembled for use without the use of any securing elements other thanthose forming an integral part of the box structure.

The invention will be best understood from aiconsideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming a part of this specificati/on, with the understanding,however, that 'the invention is not confined to any strict conformitywith the showing of the A drawings, but may be changed or modified solong'as such changes or modifications mark no material departure fromthe salient features of the invention as expressed in the appendedclaims.

In the drawings:

Figure 1 is a perspective view of a box constructed in accordance withthis invention.

Figure 2 isa longitudinal sectional view of the box.

Figure 3 is a transverse section taken upon line 3 3 of Figure 2, and

Figure 4 is a perspective view of the box in partially folded condition.

Referring now to the drawings in detail, wherein like numerals ofreference indicate corresponding parts throughout the several views, itwill be seen that the A receptacle embodying this invention is formedfrom an integral -blank of sheet material indicated generally by thenumerall.

The blank comprises a relatively long unbroken portion 2, constitutingone side wall, at each end of which there is formed a series vfoldedupW-ar ly of three sections gether panels 3 are hingedly connected tothe side wall 2.

One of the panels 5 has integrally connected thereto, b a verticalfoldone section 6 of the other si e wall of the body, through whichthere is formed, verticallyand adjacent the free end thereof, a slot 7.

The other section 5 has connected thereto, bya vertical-fold, the othersection 8 of the said other side wall, which section 8 has formed in itstop and bottom edges and adjacent the free end thereof V-shaped notches9, providing head portions 10 upon the end of this section. f

The said section 8 has, extending inwardly from the free endl thereofand along its center, a V slot 11 which, as is clearly shown, extendssubstantially the entire length of the section and provides spacedlocking tongues at the forward ends of which the head `por tions arelocated.

Formed v through the section 8 and substantially midway between the endsthereof and between the slot l1 and the lower edge is a pair of slots12, located one above the other as clearly shown in Figure 4.

Each of the panels 3 and 5 also has a slot cut therethrough andtransversely of the panel as indicated by the numeral 13, and theseslots 13 are the same distance above the lower edge of the bla-nk 1 asthe upper one of the slots 12.

Integral with and extending throughout the lower edge of the side wall 2is a web 14, which is designed to be folded upwardly against the innerside of the side wall 2, and when so folded its upper edge will\be inali nment with the slots 13;

ntegral with the upper ed e of the web portion 14 is a bottom 15 whicbottom is of greater length than the web portion 14 and side wall 2 asis clearly shown in Figurek 4. Extending from the central portion of thefree longitudinal edge of the bottom 15 is a tongue 16, designed, whenthe box is set up, to be threaded through the slots z.12 in the sidewall section 8.

-In setting u panels or sections 3, 4 and 5, which or panels arehingedly connected tothe box the web portion 14 is against the innerface of the positioning the bottom above of the body blank 1. The 5, ateach end of the bottom,

side wall 2, thus the lower edge panels 3, 4 and by vertical folds andas shown the are then folded inwardly and each corner of the bottom 15is extended through an adjacent one of the slots 13 as shown inFigure 1. The section 6 of the otherside wall is then folded inwardlyagainst the free outer edge of the bottom after which the section 8 ofsaid wall is folded against the said edge of the bottom at the other endthereof and the heads 10 of the locking tongues passed through the slot7 of the section 6.

Since the slot 7 is of a length materially less than the height of thesection 6v in which it is formed it is apparent that the upper and lowertongues which are providedthrough the for-` mation of the slot 11, mustbe brought together in order to pass the head portions 10 through theslot. After the head portions of the tongues have been passed throughthe slot, the tongues spring apart and the notches 9 will engage at theupper and lower ends of slot 7 to hold these wall sections 6 and 8 ininterlocked relation. rll`he tongue 16 of the bottom is then passedoutwardly through the upper one of the slots 12 and folded downwardlyand back'through the lower one of the slots as clearly shown in Figures2 and 3.

lit will be observed by reference to the drawings and particularly toFigures 1 and t thereoft-hat the wall sections 3 and 5 lof the box arediagonally disposed, in the set up condition of the box, and that thewall sections 4: are disposed in planes parallel to each other and atright anglesto the side wall sections of the box.

From the foregoing description itwill be readily seen that there isprovided a box having a solid wall structure, and further having abottom securely braced at six points and, therefore, not likely tocollapse easily. For the packing of berries orother very juicy or wateryfruit the inner surfaces of the box may be coated with waXor a likesubstance to pre'- vent the material of the box from absorbing thejuices of the fruit. The side wall 2 being smooth and unbroken alsopresents a surface moaois which might be readily employed for theapplication of a name or advertising matter.

Having thus described my invention, what l claim is:

1. A receptacle of the class described comprising side wall sections,end walls each including spaced diagonal sections and intermediatesections occupying parallel planes and planes at right angles to theplanes of the side wall sections, the diagonal end wall sections havinghorizontal slots therein in spaced relation to their lower edges, a webintegrally connected by a fold with the lower edge of one of the sidewall longitudinally throughout the length of said edge of said section,and a. bottom integrally connected by a fold with the other edge of theweb and of a length greater than that of the web, the said bottom beingof rectangular form and having its corner portions-projected through theslots in the diagonal wall sections. v 2. A receptacle of the classdescribed comprising side wall sections, end walls each insections andextending cluding spaced diagonal sections and intermediate sectionsplanes at right angles to the planes of the side wall sections, thediagonal end wall sections having horizontal slots therein in spacedrelation to their lower edges, a web integrally Connected by a fold withthe lower edge of one of the side wall sections and extendinglongitudinally throughout the length of said edge of said section, abottom integrally connected by a foldwith the other edge of the web andof a length greater than that of the web, the said bottom beingofrectangular form and having its corner portions projected through theslots in the diagonal wall sections, the other side wall section havinga horizontal slot-therein spaced with respect to its lower edge, and atongue upon the free edge of the said bottom engaged through said slot.A s
